Toner for development of electrostatic image, method of producing the same, electrostatic image developer, toner cartridge, process cartridge, and image forming apparatus
Abstract:
The invention provides a toner for development of an electrostatic image, which has colored particles containing a crystalline polyester resin having a melting temperature Tm1 (° C.) of approximately 50 to approximately 100° C., a non-crystalline polyester resin, and a coloring agent, the temperature Tm2 (° C.) of an endothermic peak derived from the crystalline polyester resin in a first process of raising temperature and the temperature Tm3 (° C.) of an endothermic peak derived from the crystalline polyester resin in a second process of raising temperature, in differential scanning calorimetry based on JIS K7121:1987, satisfying the following relationships (1) and (2): 0≦(Tm1−Tm2)
